Answer: The father determines the biological sex of a baby

Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.

What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.

Types of s-ex chromosomes?

There are two types i.e. males and females. In males, it has  XY chromosomes while on the other hand,  females have XX chromosomes. At the time of fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote.

Women have two X chromosomes (XX) and at any point in time they can only release an egg-bearing an X chromosome, however,  males contain one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. In this way, the process should be continued.
